The research laboratory "Group of Physics of Materials (GPM)" is a Joint Research Unit (UMR 6634) associated to University of Rouen Normandie, INSA of Rouen Normandie (both members of the federation of Normandy University) and affiliated to the French National Research Center (CNRS) as a member of the Institute of Physics (INP) and also of the Institute of Engineering and Systems Sciences (INSIS).

The laboratory has developed a strong expertise in scientific instrumentation and in material characterization down to the atomic scale, with a special emphasis on the connection between nanoscaled structures and properties.

The laboratory is organized in five Scientific Departments with an expertise internationally recognized in the following areas:

• Scientific Instrumentation
• Metallurgy, Microstructures, Mechanics
• Functional Materials and Nanostructures
• Disordered systems and Polymers
• Opening Fields and Innovations
